* g10/keygen.c (keygen_set_std_prefs): prefer SHA-512
and SHA-384 by default.
--
In 8ede3ae29a39641a2f98ad9a4cf61ea99085a892, upstream changed the
defaults for --default-preference-list to advertise a preference for
SHA-512, without touching --personal-digest-preferences. This makes
the same change for --personal-digest-preferences, since every modern
OpenPGP library supports them all.

(gen_rsa, get_keysize_range): update default from 2048 to 3072).
* g10/keyid.c (pubkey_string): update comment so that first example
is the default 3072-bit RSA.

3072-bit RSA is widely considered to be 128-bit-equivalent security.
This is a sensible default in 2017.
